By operatively connectingithe stub shaft 24 to the screw shaft 34 by the pin connection, it is possible to separate the .head Y18 from the tubes 16 ,by merely releasing the clamp 21 and which is necessary for the purpose to be present- 1y explained. A` :Yk 'Y In practice',"assume that theyparts in normal position at which time the carrier plateV is resting upon the basev'plate 11"with the tops hopper or trough 19; After the; medicinal'powe der has been mixed and is ready for packaging,

As the contents of the hopper 19 is receivedby the respectivetubes 16, moreof the powder maybe poured thereinto until the 'predetermined amount Yof thel mixture has been'equally distributed intothe respective tubes 16.- A t this time, the operator releases the clamp21,andremovesthe head 18 therefrom,

, From the foregoing description, it winfbe'sen that a druggist may compound'a medicinal pow,

dividual receivers in'order toassure an equal'dose of the mixturev in eachypackage. The advantages of this device are clearly; set forth hereinbefore, o repeat the and it is not,deemed necessary same. 5. In'the drawings, I have illustrated allineasurfing andv distributing devicecapable of putting up twenty-four doses of a medicinaljpowdered preparation, butif desired, any predetermined numbers of these receiving tubes Vmayy be masked out by the insertionlof masking disc s or membersover the head 18- to seat within the troughr or recess lolnllgsili the various masking elemet'..
